HRESULT: 0x800A03EC on Worksheet.range

Question

I am getting HRESULT: 0x800A03EC on Worksheet.range method. Number of rows are more than 70K. Office 2007.

Code:

Microsoft.Office.Interop.Excel.Range         


        

Answer 1

I don't understand the issue. But here is the thing that solved my issue.

Go to Excel Options > Save > Save Files in this format > Select "Excel Workbook(*.xlsx)". Previously, my WorkBooks were opening in [Compatibuility Mode] And now they are opening in normal mode. Range function works fine with that.
